Compounds of formula (I): Z is >CH-, >C=CH- or >N-, R1 and R2 are optionally substituted and are the same or different, and each represents an aryl group, a heteroaryl group, or Z, R1 and R2 form a fused ring structure of formula: in which A represents a single bond, or linking group, R3 represents hydrogen, a group selected from: -AIkCOOR, -AIkNR7R8, -AIkCONR7R8, -AIkCOR9, -AIkSO2NR10R10', -AIkOR10, and -AIkS(O)nR10, in which AIk is alkyl, R is hydrogen or alkyl, R7 and R8 each represents H, optionally substituted alkyl, alkylaminoalkyl or dialkylaminoalkyl, or CONR7R8 forms an optionally substituted heterocycle, and R10 and R10 are hydrogen atom, optionally substituted alkyl, an alkylaminoalkyl group, an optionally substituted cycle, optionally spaced by an AIk group as defined, Q represents >C=0 or >C=S, R5 is a hydrogen atom or an alkyl, alkoxy, hydroxyalkyl, alkylthio, or thioalkyl group, p is 1, 2 or 3, q is 0, 1 or 2, R6 represents an optionally substituted aryl or heteroaryl group, and salts and esters thereof, are useful as calcimimetics in therapy.

L'invention concerne des composés de formule (I) : Z est >CH-, >C=CH- ou >N-, R1 et R2 sont facultativement substitués et sont identiques ou différents, et chacun représente un groupe aryle, un groupe hétéroaryle, ou Z, R1 et R2 forment une structure en anneau fusionnée de formule: selon laquelle A représente une simple liaison, ou une séquence de liaison, R3 représente l'hydrogène, un groupe choisi parmi : -AIkCOOR, -AIkNR7R8, -AIkCONR7R8, -AIkCOR9, -AIkSO2NR10R10', -AIkOR10, et -AIkS(O)nR10, AIk étant alkyle, R est l'hydrogène ou alkyle, R7 et R8 représentent chacun H, alkyle facultativement substitué, alkylaminoalkyle ou dialkylaminoalkyle facultativement substitué, ou CONR7R8 forme un hétérocycle facultativement substitué, et R10 et R10 sont un atome d'hydrogène, alkyle facultativement substitué, un groupe alkylaminoalkyle, un cycle facultativement substitué, facultativement espacés par un groupe AIk tel que défini, Q représente >C=0 ou >C=S, R5 est un atome d'hydrogène ou un alkyle, alkoxy, hydroxyalkyle, alkylthio, ou thioalkyle, p est 1, 2 ou 3, q est 0, 1 ou 2, R6 représente un groupe aryle ou hétéroaryle facultativement substitué, leurs sels et leurs esters, ceux-ci étant utiles sur le plan thérapeutique en tant que calcimimétiques.
